Unbalanced might be around the limit at 7m.

Thanks Graeme, good to know that is a consideration as well.

You like to do a bit of system planning - which is quite enjoyable I get that.
You have pretty much maxed out your 200 series with super lumina Xlr and speaker cable so already wringing out the last drop of SQ.
Unfortunately, there is no NSC 333 (Iād probably buy one blind 
if it existed!) so options Iād consider, if I was you, would be potentially subwoofers or maybe 350ās.
That said itās diminishing returns at this level so personally Iād find a better value proposition for my cash.
Last year at my dealers I listened to dCS Rossini and ATC SCM 20 asl limited edition (blue ones) and whilst it was very good I preferred my system (not saying itās better though).
Good luck with whatever you decide and enjoy it.

This is a reply from a friend in the hifi community here up north about cables.
"Iāve been dabbling with active setups built around highly sensitive horns, both my own and othersā, for 10ā15 years, and for large parts of that time in a prototype phase with cables everywhere in all directions.
A couple of worst-case examples:
25m of signal cable in a tangled bundle stuffed into a cabinet on top of the power strip. This was an unbalanced signal from the preamp to a First Watt F5 driving ALE horns with a sensitivity of 113 dB/1W. Eight other signal cables, several power cables and speaker cables crossed and mixed nearby.
Iāve also had cases of equally long signal cables stuffed under and around an Accuphase A-45 and its power cable, but that was from an MC amp to the phono stage.
Class D, class A, preamps, sources and light dimmers all on the same circuit.
I have never, not once, experienced noise, hum, hiss, degraded sound quality or any other practical issuesāother than having to clean up the cable mess afterward. I have run the same system and cable chaos both in a living room with an ungrounded circuit, and in my previous listening room with a grounded, dedicated circuit.
I honestly end up quite puzzled by this whole supposed āproblem.ā
Care about other elements on your system, Not the cables.
Enjoy your weekend.
This event would have been interesting. I have active 50 but never compared them again passive, I just wanted to go active and liked what I heard.
From the wording it appears this was a past event, any comments from those present?
Paul.
Should take you there.

I believe @Farthings-cat has 9m unbalanced between his 552 and ATCs. I think ATC supplied the cable as well but Iām sure fc will confirm.

I use 7m balanced interconnects from my pre to scm40aās with no issues.
Confirmed!

If you preamp has balanced outputs and active speakers have balanced inputs, then with balanced cable distance between them is not a concern at all at least not in any normal practical domestic situation.

Absolutely 
. The more I dig into it, it looks more and more like a āswapā of NC NAP250/Titan 505ās for ATC 20ās or 40ās would be just that - both equally good, just different but not a step change āimprovementā, whatever that may meanā¦ā¦ which also means taking the p/x hit for nothing 
.
Andā¦.. the NSC222 + NPX300 is still a Ā£12k source component, canāt be that bad eh?

The question is, which equally good is better (fir you)? A particularly significant question where speakers are involved, as the can sound very different, and someone could love one well regarded, reportedly very good, speaker, yet find the sound from a different well regarded, reportedly good, speaker unbearable.

Both ATC and PMC accept balanced XLRs, in which case thereās no practical length limit. If the preamp power out is unbalanced, itās possible to add an unbalanced-to-balanced transformer.

One point I hadnāt considered until now is that the ATC 20ās weigh in at 45kg without stands 
. Given that my current 505ās are 18kg without stands and I find them more than enough to move aroundā¦ā¦.
Something to consider before considering a change.
ATB, J
According to ATCās website, they each weigh 24.3kg. Maybe you are confusing the weight in pounds.
I was looking at the LEās, again from the ATC LE page;
PHYSICAL SPECIFICATIONS
Net Weight: 27kgs/59.5lbs
Dimensions: HxWxD 450x250x425mm 17 11/16ā x 9 13/16ā x 14 3/16ā
Yet another value! I give up 
.
ATB, J
PS Doesnāt really matter anymore as Iāve decided to stay with the Titans.
Iām confused! You say thatās the sort you were quoting, yet you wrote 45kg. Anyway, keeping your Kudos sounds like the best plan, especially as you like gem so much. Maybe you want a Sigao Drive and more amplifiers. Buck the trend!
I drive my ATC SCM20PSLT with a 500DR, the performance is stunning. Not sure how the active 20s would compare, it would be an interesting experiment though.

Might it be possible to get your speakers a metre or so further apart? They look awfully close together.
